I don't know about that though. I don't like the fact we have to throw using two hands at all. Most times when I see people going for the elbow, they are effectively pulling nage down, not so much as dropping him. When they go for the shoulder it's inadvertently to push him. Seems to me counterintuitive to otoshi's objective ain't it?

And I always thought koshi was more about displacement, that we use the hips more often than not lends itself to the name.

Draw strength from stillness. Learn to act without acting. And never underestimate a samurai cat.
